C9 ChampionWomen's Medium Support Seamless Cami Bra

I bought this sports bra specifically for the narrow straps and racer back. I have several similar sports bras that aren’t being sold anymore and thought this would be a good replacement. I’m 5’10, around 172lbs, bra size 36A. I typically wear a size M or L in womens tops depending on the fit/style. Because I’m so small chested I don’t need a ton of support but have noticed my old sports bras were very stretched out and maybe too comfortable. I bought them years ago at Old Navy in size L. For this bra I bought a L and XL because of all the people stating that it runs small. According to the size chart I should have fit a M. I tried both on and the L is TIGHT. Not so tight I can’t breathe, but it was not easy to just pull on. XL felt more stretchy and comfortable and more like my old sports bras. I finally decided to go with the L as I was really looking for more compression than I currently have. I just finished a 5 mile run and my boobs absolutely did not move while I was running. I also noticed the creaking noise at the back ring others have mentioned but did not hear this while I was running or while I was doing yoga after. Sitting here though I can make the creaking start by moving my shoulders. I took out the pads immediately (never use them) but haven’t had visible nips due to how snug the bra is. Overall I’d recommend this for low intensity workouts for everyone or high intensity for smaller breasted women, just be prepared to size up!!

This is one of my fave sport bras and it is also one of the cheapest that I have. I have 2 colors and they wash and last well and the cup inserts stay in place and don't move around. I am 5'5", 130 lbs, 34D and the M fits great. I have black and grey. I tried white, but it was too see through.

It’s a good-looking top, and I love that it has adjustable straps, but my XXL ran too small, to the point where it was uncomfortable. If they made this about two sizes bigger, I could have gotten that, or if I were a Medium, I probably would have been in business with the XXL. If I’d found one that fit me, I think I would really have liked it.

This bra is the most comfy bra I’ve ever worn. It is soft and you can’t really feel it on you. I do recommend this bra, best bra I’ve ever had. It’s so comfortable, will buy again! 😁

I normally wear a Large. Bought this in a large and couldn't get it on it was so tight. Was disappointed because I like the style and fabric. Runs small.

I've been buying these sports bras for years and was really disappointed when Target stopped carrying C9. But Amazon to the rescue! The material is soft and stretchy and these provide perfect support for daily activities. I'm 34D and wear a medium. These bras provide light/moderate support and I wear these working out (not running) and honestly they are comfortable enough that I could and have worn on a daily basis.

I have several Champion brand sports bras in a smaller size that I've enjoyed wearing for a long time. Lately, I've been disappointed buying new sports bras -- they seem to be extremely tight and tiny. I know I wear size S in Champion, so I ordered M -- but this too seems made for a child.If I hold one side under my arm and try to stretch it across my chest, it barely gets past the center before the elastic strains. Wearing it is like having pneumonia -- I can't take deep breaths!! Absolutely NOT what a sports bra should be. As for appearance, it squishes my 'girls' so that I look ridiculous.I don't think I can return it now -- the effort to get it on and off left deodorant marks -- so I'll just advise, be careful. For the record, I'm 5'3, 108 lbs, 34B.

These are exactly what I was looking for! I'm 128lb, 5'6" and a 34B, and the medium fits me perfectly. After wearing maternity and post-maternity nursing clothes with two babies, I've gotten so used to comfortable, loose-fitting clothes that I just can't go back to the tighter clothes I used to wear, and that includes my sports bras. I'd definitely say this bra is medium support at the most, but that works fine for me even with running or other high-impact sports since I can barely fill a B cup haha.I got the mauve and the ebony black, and I'd say the ebony one feels just the tiniest bit tighter since it's made of a slightly different material combination. But they both fit great and are comfortable and supportive enough to be worn around the house, while exercising, or while sleeping.

This is my favourite brand for sports bras and this is my favourite style, I have 3 of this style alone. The pink one was more purple in real life but still very cute. Great for larger bust as well

Tight enough for compression and support, and super comfortable.

Based on other reviews, I bought size L in this bra. The bra itself is good if you don't mind inserts in the cups. The sizing, however, is indeed very small. I wanted a tight fit so I'm going to keep this but it is very tight. If I were in a store and had the XL nearby, I'd definitely try that one on as well.UPDATE: after wearing once, L fits great now. I guess it noticeably stretches out.

Comfortable and quality sorts bra. Not for high impact sports but I like the fit and quality of the product.

Just too tight for a medium
